A 'double-balloon enteroscopy worth the money': endoscopic removal of a coin lodged in the small bowel.

Double-balloon enteroscopy (DBE) has become the standard endoscopic method to diagnose and treat disorders of the small bowel. The most common therapeutic applications of DBE are hemostasis, polypectomy and stricture dilation. DBE has also been used to place stents in the small bowel and to retrieve foreign bodies such as retained capsule endoscopes.
